Abstract Magnetic resonance imaging (MRI) technology has profoundly transformed current healthcare systems globally, owing to advances in hardware and software research innovations. Despite these advances, MRI remains largely inaccessible clinicians, patients, researchers low‐resource areas, such as Africa. The rapidly growing burden of noncommunicable diseases Africa underscores the importance improving access equipment well training opportunities on continent. Consortium for Advancement...
Smaller, more affordable, and portable MRI brain scanners offer exciting opportunities to address unmet research needs long-standing health inequities in remote resource-limited international settings. Field-based neuroimaging low- middle-income countries (LMICs) can improve local capacity conduct both structural functional neuroscience studies, expand knowledge of injury neuropsychiatric neurodevelopmental disorders, ultimately the timeliness quality clinical diagnosis treatment around...
The potential of graphene oxide–Fe3O4 nanoparticle (GO-Fe3O4) composite as an image contrast enhancing material in magnetic resonance imaging has been investigated. Proton relaxivity values were obtained three different homogeneous dispersions GO-Fe3O4 composites synthesized by precipitating Fe3O4 nanoparticles reaction mixtures containing 0.01 g, 0.1 and 0.2 g oxide. A noticeable difference proton was observed between the cases. comprehensive structural characterization revealed discrete...
To retrospectively evaluate the fidelity of magnetic resonance (MR) spectroscopic imaging data preservation at a range accelerations by using compressed sensing.The protocols were approved institutional review board university, and written informed consent to acquire analyze MR was obtained from subjects prior acquisitions. This study HIPAA compliant. Retrospective application sensing performed on 10 clinical sets, yielding 600 voxels six normal brain 163 two tumor 36 prostate cancer sets...
Magnetic Resonance Imaging (MRI) is a critical component of healthcare.MRI data acquired by playing series radio-frequency and magnetic field gradient pulses.Designing these pulse sequences requires knowledge specific programming environments depending on the vendor hardware (generations) software (revisions) intended for implementation.This impedes pace prototyping.Pulseq (Layton et al., 2017) introduced an open source file standard that can be deployed Siemens/GE via TOPPE (Nielsen & Noll,...
Abstract Measuring parameters like magnetic field strength and temperature inside a magnet bore is of interest to characterize the system use that information for downstream image quality improvement or determine safety thresholds. Multiple commercial measurement systems are available achieve this goal. However, these often expensive, utilizing proprietary hardware software, making adjustments specific applications challenging, if not prohibitive. In work, we design, build, test simple, MR...
To enhance the nutraceutical value and preservation of mushrooms, this study focused on augmenting two widely consumed mushroom varieties in India namely Button Mushroom (Pleurotus ostreatus) Oyster (Agaricus bisporus). These mushrooms were subjected to UV light exposure evaluate their impact phytochemical content, including phenolics, flavonoids, folic acid, Vitamin D2. The percent increase phenolic content after 120 minutes treatment was 0.6-fold for Agaricus bisporus 0.7-fold Pleurotus...
Purpose To compare the bias and inherent reliability of quantitative (T 1 T 2 ) imaging metrics generated from magnetic resonance fingerprinting (MRF) technique using ISMRM/NIST system phantom in an international multicenter setting. Method MRI provides standard reference relaxation values (vendor‐provided) for each 14 vials arrays. MRF‐SSFP scans repeated over 30 days on GE 1.5 3.0 scanners at three collaborative centers. MRF estimated 1, averaged were compared with vendor‐provided...
Magnetic Resonance Spectroscopic Imaging (MRSI) has wide applicability for non-invasive biochemical assessment in clinical and pre-clinical applications but suffers from long scan times. Compressed sensing (CS) been successfully applied to 1H MRSI, however a detailed evaluation of CS conventional chemical shift imaging is lacking. Here we evaluate the performance accelerated specifically apply it accelerate 23Na-MRSI on mouse hearts vivo at 9.4 T. Synthetic phantom data representing...
Abstract To compensate the limitations of bone tissue magnetic resonance imaging (MRI), a series gadolinium (Gd 3+ ) substituted β ‐Tricalcium phosphate [ ‐TCP, ‐Ca 3 (PO 4 2 ] were developed. All powders characterized using XRD, Raman spectroscopy, Rietveld refinement XRD data and studies confirmed Gd occupancy at Ca 2+ (1), (2) (3) lattice sites 2. HR‐TEM analysis revealed spherical nature particles with diameter about 100 nm. The doped exhibited non‐toxic behaviour to MG‐63 cells in vitro...
